Snow Quartz

Snow Quartz represents our premium-grade Quartz offering, characterised by exceptional whiteness and very low iron content. This high-purity grade is suited for applications where visual brightness and chemical purity are critical — including premium glass, high-end ceramics, decorative aggregates, and select cosmetic or filler applications. The superior whiteness index and minimal Fe₂O₃ content are what differentiate Snow Quartz from standard and semi-super grades.

Industries We Supply

Where These Minerals
Are Used

Quartz and Silica are among the most widely used industrial minerals globally — essential raw material inputs across six major manufacturing sectors.

🪟
Glass Manufacturing
Silica is the primary raw material in glass — SiO₂ forms 70–75% of the glass batch. Snow Quartz and Silica Sand with low Fe₂O₃ are critical to producing clear, colourless container and flat glass.
Snow QuartzSilica SandSemi Super Quartz
🏺
Ceramics & Tiles
Quartz is a key component in ceramic body formulations, improving mechanical strength, thermal stability, and dimensional accuracy during firing. Higher-purity grades improve whiteness of the final product.
Semi Super QuartzSnow QuartzQuartz
⚙️
Foundry & Metal Casting
Silica Sand is the base material for green sand molds used in metal casting. Quartz powder is also used in investment casting and shell molding for high-precision castings.
Silica SandQuartz
🏗️
Construction
Quartz and Silica Sand are used in concrete, plaster, mortar, and as aggregate in construction applications. Higher-purity grades go into engineered stone countertops and decorative surfaces.
Silica SandQuartz
⚡
Ferrosilicon & Metallurgy
High-SiO₂ Quartz is used as a raw material in the production of ferrosilicon alloys — an important additive in steel manufacturing to improve strength, corrosion resistance, and castability.
QuartzSemi Super Quartz
💧
Water Treatment & Filtration
Silica Sand is a standard filter media in water treatment plants, swimming pools, and industrial water filtration systems — selected for grain size consistency, chemical inertness, and durability.
Silica Sand
Sourcing & Quality

From Rajasthan's Quartz
Belt to Your Facility

A transparent, documented supply process — from mine to export port.

01
Mine Sourcing
Direct relationships with quartz mines and processing units across Rajasthan's established quartz-producing mineral belts — ensuring consistent quality at the source.
02
Crushing & Grading
Quartz lumps are crushed, screened, and graded to the required particle size or mesh specification. Powder grades are milled to -200 or -325 mesh as required.
03
Washing (Silica Sand)
Silica Sand is washed to remove clay, silt, and surface impurities, then dried and screened to consistent grain size distribution for buyer-specified AFS numbers.
04
Chemical Testing
Pre-shipment sampling and chemical analysis through accredited laboratories — SiO₂, Fe₂O₃, Al₂O₃, moisture, and whiteness index tested per product grade.
05
Packaging
Available in 25kg/50kg HDPE/PP bags, 1MT jumbo bags (FIBC), or bulk container loading — sealed and labelled to buyer specification with batch and grade identification.
06
Export Documentation
Commercial Invoice, Packing List, Bill of Lading, Certificate of Origin, CoA, and test reports — shipped via Mundra, Kandla, or JNPT on FOB, CIF, or CFR terms.
